Problems solved by technology

Usually, when the piston of the hydraulic cylinder inside the damper is moved by the piston rod, the volume of the front and rear chambers of the piston changes, and a pressure accumulator is required to compensate the volume. The structure is more complicated, and the damping size of the damper is fixed. restricted

Abstract

The invention discloses an adjustable damper, and relates to the field of damping. The upper end of a piston rod extends out of the upper end of a cylinder body and is connected with an upper connecting head; the cylinder inner cavity of the cylinder body is provided with an oil passage; an inner cover in threaded connection with the cylinder inner cavity of the cylinder body is arranged in the middle part of the piston rod; a space formed by the inner cover and the cylinder inner cavity is filled with a damping liquid; an outer cover is installed at the lower end of the piston rod; a spring is arranged between the inner cover and the outer cover; a lower connecting head is in threaded connection with the cylinder body; a spring is arranged between the outer cover and the lower connectinghead; and an adjusting screw is arranged on a boss on the outer side of the cylinder body. According to the adjustable damper, the piston rod and the outer cover do linear reciprocating motion in thecylinder inner cavity of the cylinder body, and the damping liquid flows back and forth through the oil passage, so that damping is generated and energy is consumed; when the adjusting screw is rotated, the section area of the oil passage is changed because of the head of the adjusting screw, and the generated damping force is also changed; and the adjustable damper is simple in structure, a pressure storage device is canceled, and the springs at the two ends of the outer cover enable the damper to be provided with a reset function during bidirectional action of the damper.

Description

technical field [0001] The invention relates to the technical field of damping and shock absorption, in particular to an adjustable damper. Background technique [0002] A damper is a device placed on a structural system that can provide movement resistance and is used to reduce movement energy. It is widely used in aerospace, aviation, military, guns, automobiles and other industries. Usually, when the piston of the hydraulic cylinder inside the damper is moved by the piston rod, the volume of the front and rear chambers of the piston changes, and a pressure accumulator is required to compensate the volume. The structure is more complicated, and the damping size of the damper is fixed. restricted. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an adjustable damper which cancels the pressure accumulator and has adjustable damping and reset functions. [0004] In order to achiev...
